![]() ![]() All windows to be rendered are represented as composition nodes in a composition tree. MIL is also used to draw Avalon/WPF applications and therefore is sometimes also referred to as a Unified Compositing Engine (UCE). The actual image is drawn by an unmanaged compositor, the Media integration Layer (MIL). A good example of the latter are the live tool-tips as seen in Vista and later. Because every application’s buffer is constantly updated, even when not directly in sight, it’s possible to show live-preview images in other applications. Since the compositing window manager has access to all image information on the system, it’s extremely easy to add 3D effects to all applications on the system. The window manager then composites all buffer information into an image which is displayed on your screen. Once the window manager receives drawing information from an application, it draws this information to a buffer. What’s unique about a compositing window manager is in the fact that it provides a buffer for each application visuals. A window manager manages the windows that you see on your screen. Desktop compositing in generalĭesktop compositing is a special type of window manager. You might want to try installing another driver or another VMware version altogether. If one of the two features cannot be enabled, something is wrong. The Notes section will show detailed descriptions whenever there are problems with the current driver. Note that both DirectDraw and Direct3D are supported and enabled using the Vmware. On the Display tab you will find the current status of all DirectX features. Whether these two features are supported and enabled can be checked in the DirectX diagnostic tool. If you followed above steps correctly (and the display driver supports it) and Longhorn plays along nicely you should now have support for DirectDraw and Direct3D. Move the slider completely to the right (Full). Right-click on the desktop > Properties > Settings > Advanced > Troubleshoot In build with a Server SKU however, you need to set this by hand. In client builds this is often on by default, and you don’t need to set this yourself. Have trouble installing the driver? See this guide. Most of the time display driver 6.5.2 will work on any VMware version just fine. ![]() Go to the settings of the machine and under Display check the box to accelerate 3D graphics.įrom the list at the bottom of this page pick a combination of VMware version and display driver version. Your virtual machine will need to be off to change this setting. To make matters more complicated, when virtualizing, the version of the hypervisor may also influence if desktop compositing works at all. This is why it’s very important to have the right driver installed. These are the two things we want to have working.Įven when the hardware supports the above points, the driver may limit these features. There are a couple of things we need to make sure are supported and working before desktop compositing will work. Personal experience shows that the following graphic cards work very well with Longhorn and do allow desktop compositing.įor both Nvidia cards driver I recommend driver version 61.77. You may need to install the driver package in Windows XP compatibility mode (right click > properties > compatibility). Moreover, there should be Windows XP drivers available for it. Your computer should at least have a graphics card with Pixel shader 2.0 and DirectX 9 support. For some builds desktop compositing may even work out of the box. In the case you have some old Longhorn-era hardware, it is worth the effort to try and get desktop compositing working. Feel free to share any combinations not listed on this page in the comments section! If you came here looking for drivers, they can be found at the very bottom of this page. Note that it’s very well possible that other combination work out for you. For each of these build I will list the combination of VMware version and display driver that worked for me. At the bottom of this page you’ll find a list of builds that have working desktop compositing. ![]() ![]() As such, all drivers provided on this page are meant for use with VMware. I’d like to note that I am writing this tutorial with VMware workstation in mind. In this tutorial you will find everything you need to enable desktop compositing on the Longhorn builds that support it. ![]()
